SMOKE-DISTRIBUTER.

SPECIFICATION forming part of Letters Patent No. 670,580, dated March 26, 1901.

Application filed January 23, 1901. serial No. 44,335. (No model.)

T0 all whom it may concern:

Be it known that I, MELVIN B. COPE, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Smoke-Distributers; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to prevent discoloration of ceilings by providing simple, economical, and attractive means for intercepting and distributing smoke arising from chimneys inclosin g flames of material burned for illuminating purposes, said invention consistingin certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a partlysectional elevation of mechanism in accordance with my invention for the interception and distribution of smoke. arising from a chimney employed to inclose an illuminating flame, the sectional portion of the view being indicated by lines 1 1 in the second figure; Fig. 2, a plan view of said mechanism, partly in section, on lines 2 2 in the first figure; Figs. 3 and 4, detail perspective views of parts of a framework embodied in said invention, and Fig. 5 a similar view of a portion of a stand for the framework and parts in connection therewith.

Referring by letter to the drawings, A in- I dicates a stand preferably made from strands of suitable wire twisted together to form a central vertical stem and bent outward from the lowest portion of the stem to provide horizontal radial stem branches having downturned outer ends. The stand, is designed to fit upon the upper edge of a chimney of the kind herein set forth, and extending upward from the stem portion of said stand central of the same is a pivot 13' for the support of mechanism hereinafter particularlydescribed. The pivot may be permanent with the stand; but the upper central stem portion of said stand is preferably made to form a socket in which to seta removable pivot, it being practicalto furnish substitute pivots with each stand or to utilize ordinary sewing-needles or decapitated pins to replace pivots that become broken or otherwise unserviceable.

The upper horizontal portion of a yoke C is provided with a central indentation Z), engaged by the point of pivot B, and downwardly-diverging branches of the yoke are-in union with a horizontal centrally-apertured plate D, having a series of radial arms the outer ends of which are in the form of clips 0, set at an angle to the horizontal plane of said plate and below the same, as shown in Fig. 1. Between its aforesaid branches the upper horizontal portion of yoke O is shown provided with depending ears d, and outwardly-extending spring-clips E are engaged with said ears.

So much of the above-described framework as comprises the yoke C and plate D is herein shown as being made from sheet metal, the yoke branches being made with lower ears 6, that engage plate-slots fand-are horizontally bent to clench said yoke in place. When of sheet metal, the outer ends of the radial arms of plate D are made sufficiently wide to be bent over on themselves in a longitudinal direction to form the clips 0 aforesaid.

Segmental blades F, of mica or other suitablematerial, are engaged with the clip ends 0 of the radial arms of plate D to form a propeller-wheel, the pitch of the blades being determined by the angle of said arms. A plate'G, of mica or other suitable material, engages the spring-clips E to constitute a vertically-disposed fan, the design of which may be that herein shown or otherwise, as best suited to the demands of the trade.

The herein-described mechanism assembled as best illustrated in Fig. l is set over a chimney employed to inclose a flame of material burned for illuminating purposes, and a draft of air resulting from combustion within said chimney acts upon the propellerwheel to rotate the fan, whereby smoke issuing from the aforesaid chimney is intercepted and forcibly distributed in all directions radially from said mechanism to be dissipated in the surrounding atmosphere before it can attack the ceiling of an apartment in which said flame is utilized.

' IOO Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a stand made to rest on the upper edge of a chimney for an illuminating-flame and provided with an upper central pivot, a framework loose on the pivot, propellel wheel blades in connection with theframework, and a fan-plate alsoin eon nection with said framework above said blades.

2. The combination of a stand comprising a central stem having branches extending radially from its lower portion and turned down at their outer ends, a pivot rising from the upper central portion of said stem, a framework loose on the pivot, propeller-wheel blades in connection with the framework, and a fan-plate also in connection with said framework above said blades.

3. The combination of a stand comprising a stem having an upper central socket, and radial lower branches turned down at their outer ends, a pivot in detachable engagement with said socket, a framework loose on the pivot, propeller-wheel blades in connection with the framework, and a fan-plate also in connection with said framework above said blades.

4:. The combination of a stand made to rest on the upper edge of a chimney for an illuminating-flame and provided with an upper central pivot, a yoke having an upper horizontal portion thereof provided with a central indentation engaged by said pivot, a centrally-apertured plate in union with depending branches of the yoke and having radial arms at angles to its horizontal plane in a downward direction the outer ends of these arms being in the form of clips, propeller-wheel blades engaging the clips, other clips in connection with the aforesaid yoke, and a fan-blade engaging the latter clips.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwau kee and State of \Viscousin, in the presence of two witnesses.

MELVIN B. COPE.
